Abstract: ) An overhead electric conductor comprises a central tubular metal core 52, at least one layer 55 of helically wound bare metal wires surrounding the core and, loosely housed in the bore of the core, at least one optical fibre element 11. The optical fibre element 11 comprises a flexible tube 17 of elongate transverse cross-section in which is loosely housed an optical fibre ribbon structure 12 and which is resiliently set in such a form that it follows a path of smoothly curved undulations, the axes of curvature of which lie parallel to one another and normal to the axis of the tube. Should a tensile force applied to the overhead conductor be transferred to the loosely housed optical fibre element, the flexible tube of the element will tend to straighten in a lengthwise direction against the action of its resilient set thereby to reduce any tensile force that might otherwise be applied to the optical fibres and, when the tensile force is removed, the tube will return under the action of its resilient set towards its original form.

Filed: 1989-06-05
Abstract: The problem with single cartridge dispensers is that when a maintenance person looks at the liquid level of the cartridge, the fluid may be only slightly above the level indicator window with the result that the cartridge would be completely used up before the maintenance person returns to service the dispenser. Thus, it would be desirable to have two cartridges so that the user can completely exhaust one cartridge and then begin dispensing from the second cartridge. The device (10) employs two cartridges (11a,11b) each having a compressable dispensing pump (25a, 25b). A movable compression member (52) is slidable to a first position adjacent the pump (25b) of a first cartridge (11b) or to a second position adjacent the pump (25a) of the second cartridge (11a) so that fluid from only one cartridge may be dispensed at a time.

Granted: 1994-02-15
Abstract: Abstract A computer connected to an ISDN switch via an ISDN digital subscriber line, has shared call appearances with a number of telephone stations connected to the switch and on the basis of shared call appearance associated messages from the switch, controls the forwarding of calls directed to the stations with which it has a shared call appearance. The associated messages are interpreted by the computer,which generates station status information. The computer responds to messages associated with predefined ones of the stations to select an alternate destination for the call and to transmit ISDN messages to the switch to cause the call to be forwarded to the selected alternate destination. Calls may be forwarded depending on call type, called number or other criteria. The computer responds to calls forwarded to it in the event that an associated station is busy and connects a holding party to the principal phone when the principal phone is no longer busy. The computer may be connected simultaneously to several ISDN switches via ISDN subscriber lines to receive shared call appearance associated messages from the several switching systems and forward calls for a telephone station connected to one switch, to a telephone station connected to another switch.

Granted: 1994-09-27
Abstract: A rotary vibration damper for a shaft has a flywheel ring, a hub, circumferentially evenly distributed first resilient elements for interconnection of the flywheel ring with the hub and second resilient elements of substantially columnar shape which are located between the first resilient elements.  The second resilient elements each have one end affixed to the hub and with the other end to the flywheel ring and are inwardly curved between their ends when the rotary vibration damper is at standstill.  The curvature is progressively straightened out with increasing speed of rotation of the rotary vibration damper by the centrifugal force acting on the second resilient elements. This straightening provides for a pretensioning of the second resilient elements and, thus, for an increased spring rigidity of the rotary vibration damper.  The rotary vibration damper has an improved long term durability and a good out-of-balance behaviour.

Title: Low cost digital amplitude regulator

IPC: H03G3/20

Granted: 1994-03-22
Abstract: A Low Cost Digital Amplitude Regulator Abstract Apparatus for digital amplitude regulation is disclosed, for use as a volume control or the like, utilizing pulse width modulation to control signal transmission through a two terminal non-linear element, the resistance of which varies with current, e.g., a diode or diode like element. A stream of pulses, the duty cycle of which is variable and digitally controlled, is filtered to produce a quasi-continuously variable reference signal. The value of the reference signal regulates gain by controlling the component of the signal of interest that is actually available for amplification. For low cost implementation in a system already employing a microprocessor or microcomputer the determinative duty cycle can be derived under software control and supplied as all output from a single latchable output pin. In an exemplary implementation, a derived DC component of the variable duty cycle pulses controls the DC output voltage from a voltage divider and is used to regulate the magnitude of a series of fixed magnitude pulses. Additionally, the use of anenergy storing type filter allows the the continuous stream of variable duty cycle pulses to be momentarily interrupted so that a pin used for supplying the pulses can be used for the performance of additional functions without affecting the perceived volume level (Fig. 1).

Filed: 1991-05-15
Granted: 1994-07-05
Abstract: ABSTRACT          A broadly tuned transducer system for pulse echo ranging systems has a rigid plate, to a planar radiating front surface of which is applied at least one layer of acoustic coupling material having a density intermediate between that of the plate and an atmosphere into which the transducer is to be coupled.  Three or more driver assemblies spaced apart in a two dimensional array are rigidly secured to a rear surface of the plate,  each assembly having a loading block and a piezoelectric element compressed between the block and the plate.  The driver assemblies all have the same resonant frequency on axes perpendicular to the plate and are driven in phase; they occupy not less than one fifth and not more than four   fifths of the area of the rear surface of the plate, which is rigid enough to prevent the excitement  of  significant  flexural  oscillations.    The arrangement permits the transducer to have a large planar radiating surface whilst using quite small piezoelectric elements.
